I am using CentOS 6, and postfix mail server, from postfix mail log, I want to see which Linux user has sent specific email, is it possible? How can this be done?

I need this to prevent spam from our mailservers, by one of our users. I need to figure out which user, and what script.

Since you know which email you are looking for (you should know its ID from the message header), you can simply find it in postfix mail log located in /var/log/mail.log - just look for the message ID in the log.
